GREAT news! Thanks. I have a set coming soon for the wifes ride. I did some poking around about Pro Maxx. I liked what I read and crossed the fingers that these bare China purchased heads were done and finished with American Pride.

If the below is true and accurate, this will make for a really good street head.

I contacted him by email with a few questions and I got good response in a timely manner. I also found out that he says he carries a wide selection of springs to fit multiple applications (I was asking about solid FT). It isn't just a generic Hyd FT or Hyd Roller choice so there is a level of custom service available that you aren't going to get from ebay vendors. Going to be an interesting choice between these and the TF whenever they happen.
